Furosemide is a loop diuretic. The diuretic effect of furosemide (Lasix) is mediated by the Na-K-2Cl-Cl-Mg-H+-Cl-HCl-Cl-Cl-H2O2-Cl- system. This system has been shown to be involved in the elimination of water, electrolytes, proteins and nucleic acids from the body. When furosemide is used to treat heart failure, this effect of furosemide is reduced. It is also reduced in patients with renal failure.
A total of 8,900 patients with HF and 8,900 with chronic HF were studied in the UK with the use of a loop diuretic, furosemide (Lasix). A total of 1,300 patients were treated in a loop diuretic. The mean time of administration was 12.8 hours, and in this study, the mean blood volume was approximately 11 L (see Figure 1). The mean clearance of furosemide (Lasix) was approximately 15 mL/kg/min, with a median clearance of 20 mL/kg/min. The mean volume of distribution was approximately 1 L (see Figure 2). The mean plasma concentration of furosemide was approximately 4.6 times greater than that of lasix (Table 1). There were no differences in the clearance of furosemide between the different treatment groups. The mean plasma clearance of furosemide was about 3.6 times greater in the treatment group compared with the placebo group (Table 1).
Figure 1: Mean blood volume and plasma furosemide clearance. Mean blood volume was measured in the loop diuretic group, the placebo group, and the treatment groups in the two clinical trials. The black line is the mean blood volume in the treatment group, and the blue line is the mean blood volume in the placebo group. The difference in blood volume between the groups was not statistically significant.
The mean time to diuresis in the furosemide group was approximately 12 hours (see Figure 2). The plasma clearance of furosemide was approximately 15 mL/kg/min in the placebo group. The plasma clearance of furosemide was approximately 11 mL/kg/min in the treatment group. There was a small but statistically significant difference in the plasma clearance of lasix between the treatment groups, but there was no difference in the clearance of furosemide between the groups. The mean time to diuresis was similar between the treatment groups.
The mean time to diuresis in the lasix group was approximately 12 hours (see Figure 2). The plasma clearance of lasix was approximately 10 mL/kg/min in the placebo group. The plasma clearance of lasix was about 11 mL/kg/min in the treatment group. There was a small and statistically significant difference in the plasma clearance of lasix between the treatment groups, but there was no difference in the clearance of lasix between the groups.
The plasma clearance of lasix was approximately 15 mL/kg/min in the placebo group. There was a small but statistically significant difference in the plasma clearance of lasix between the treatment groups, but there was no difference in the clearance of lasix between the groups.

It is used to treat edema (excessive water accumulation) and high blood pressure. Edema can be caused by various underlying issues such as heart, lung, kidney, or liver problems. This helps the kidneys to remove excess water, which is not needed by the body.

They are most commonly used as part of the medical management of congestive heart failure and other conditions where the body is retaining too much fluid.
Furosemide Tablets are flat faced, white circular tablets with bevelled edges. They are scored with a half break line for accurate dosing.

Furosemide Tablets 40mg are indicated for the treatment of oedema associated with cardiac insufficiency, renal dysfunction, and trauma in cats and dogs.
Contra-indicationsDo not use in acute glomerular nephritis, in electrolyte diseases, in patients with anuria, or patients that have received excessive doses of cardiac glycosides. Because of the danger of potentiating their toxic effects do not use with aminoglycoside or cephalosporin antibiotics. Allergic reactions have been associated with use with sulphonamides.
Special WarningsThe patient may increase its water intake to compensate for the diuresis. Consideration should be given to restricting water intake if the patient's condition makes such a course appropriate.
Special PrecautionsSpecial precautions for use in animals:Prolonged dosage may on occasions justify potassium supplementation and thus monitoring for hypokalaemia should be considered, especially if the product is used in conjunction with cardiac glycosides.Special precautions to be taken by the person administering the medicinal product to animals:Wear gloves or wash hands immediately after handling tablets. In case of accidental ingestion seek medical attention and show product label and/or pack insert to the doctor.
Adverse ReactionsNone reported
Pregnancy and LactationThe safety of use in pregnancy is not well established and a careful assessment of the likely benefits and potential risks should be made. A deleterious effect on lactation is to be expected, particularly if drinking water is restricted. Furosemide passes into milk, but not to a great extent.
InteractionsPotential interactions with other drugs include ototoxicity with aminoglycosides and nephrotoxicity with cephalosporins. Use in combination with sulphonamide treatment may lead to sulphonamide allergy. There is a possibility of interaction with cardiac glycosides.
Amounts to be Administered and Administration Route5mg/KgBW, one or two times per day. For patients weighing less than 8Kg dosage with the 20mg tablet (which may be halved) is recommended. Avoid overdosage in weak and old patients.
OverdoseDehydration and electrolyte depletion may occur. Monitor and correct, as necessary. Dosage higher than that which is recommended, may cause transitory deafness. Cardiovascular side effects may be observed in weak and old patients following overdose.
Withdrawal PeriodsNone for these species.
